The object of 7-Up is to build suits based on the seven card in each, from six to Ace, and from eight to King. The first player to get rid of all the cards in his hand is the winner. It won't be as easy as all that, though.
You've got to think about how to get your opponent to lay down cards you need, while not doing the same for him. Pass if necessary, and look to your next turn.
Keep your eyes peeled for the rapidly changing character expressions too. You'll especially want to make note of the character's expressions, such as Rei and Asuka. You need give-and-take to win this game, and nobody will be smiling all the time.
You can affect their reactions in lots of ways: pin them down and make them squirm, let them think they're winning, etc.
These Wild Cards are unique to Bonjourno 7-Up. If the Binding Card is played, for example, then the player who played it can prevent the other players from playing any cards except those of the first suit played, for one turn, giving that player a chance to turn things around in one fell swoop. There are lots of other Wild Cards as well, such as the Exchange Card, which enables the player using it to swap cards with the player of his choice.
When you win a game, you receive points depending on how well you did, instead of prizes. Once you reach a certain threshold, you can use those points for lots of different effects, such as buying the aforementioned Wild Cards at the Shop. You can also sell cards you have no use for, and get more points instead, as well as buy bonus wallpaper patterns, card backings, and other stuff. Make your selections as intelligently as you can.
